PATENT OFFICE,

BRUSH.

SPECIFICATION forming part of Letters Patent No.334,336, dated January12,1886.

Application filed February 20, 1885. Serial No. 156,543.

To all whom, t may concern:

Be it known that I, Joan FRANCIS Bow- DITCH, of Revere, in the county 0fSuffolk, in the Commonwealth of Massachusetts, have invented 4a new anduseful Improvement in Brushes; and I do hereby declare the same to bedescribed in the following specification and represented in theaccompanying drawings, of which- Figure is a front view, Fig. 2 ahorizontal section, and Fig. 3 a transverse and longitudinal section, ofa brush provided with my invention, the nature of which is defined inthe claims hereinafter presented.

In constructing the said brush I first insert between the strips orpieces of wood a a a metallic plate, and place the three in the middleofthe upper part of a mass of bristles, c, encompassed by a ferrule orhoop, d, to project somewhat above such mass, as represented. Thisferrule I have channeled or grooved on each of its opposite sides at thelower part thereof and on the inner surface of such, as shown at h, thechannel being to receive within it and to hold in place a piece of roundwire, z', to extend from end to end of the ferrule and to bear againstthe next adjacent side of the mass of bristles. Next, I drive nails ethrough opposite sides of the ferrule, the mass c of bristles, and thestrips a a, and against the metallic plate b, so as to cause such nailsby such plate to be clinched at their points upon the pieces a a. Havingdone this, I insert the pieces of wire inthe channels h h, and alsoinsert a wedge, f, between the metallic plate b and one of or each ofthe pieces a, and drive in such wedge or wedges, so as to spread thepieces c a and the mass of bristles apart with` in the ferrule, in whichcase the said mass will also be forced laterally against the two piecesof wire. Prior, however, to inserting the bristles within the ferrule,the mass at its upper part is to be dipped in a suitable liquid cement,to cause it to subsequently adhere to the inner surface of the ferruleand the outer surfaces of the pieces a a, and also to cause the bristlesof the mass where within the ferrule to adhere to each other. Next, thebase part of the handle A is to be inserted within the upper part of theferrule, so as to cover the heads of the bristles and the upper edges ofthe plate (No model.)

b, the wedge f, and the pieces a a, cement, if necessary, being rstapplied to the base of the handle or part to enter the ferrule. Nailsare next to be driven through the ferrule into the base part of thehandle, in order to conne the handle to the ferrule. In some cases,before driving the wedge f between the strips a a, I remove from themthe metallic strip b,-

Abut, generally speaking. I prefer to allow it to remain in its placebetween such strips, for after having driven the wedge between themetallic plate b and one of the strips a the nails generally have to bedriven farther in, for, owing to the compression of the bristles in theferrnle, such nails become started somewhat back or loosened in theferrule.

I am aware that it is not new to form in a tapering or wedgeshaped headof a brush a recess to receive, temporarily, a metallic or clinchingplate, and to have such head and plate inserted within a mass ofbristles encompassed by a ferrule, and also to have nails driven throughthe opposite sides of such ferrule into and through the mass ofbristles, and into the head and against the metallic plate, whereby bysuch plate the points of the nails become clinched, all being asrepresented in the United States Patent No. 207,786, dated September 3,1878, and granted to John L. Whiting. Although such a mode of making abrush in some respects is analogous to mine, it differs in othersessentially therefrom, as I do not form in the bruslrhead a recess toreceive the clinching-plate; but I use two`separate strips of wood andplace the plate between them, and the whole within the mass of bristlesand the ferrule encompassing such, and after having driven through theferrule, the bristles, and the two strips, and against theclinching-plate the nails for securing toget-her the said ferrule,bristles, and strips, I employ a wedge or wedges to force apart the twostrips. y In some cases-I have this wedge or wedges attached to and toproject directly from or to be i-n one piece with the handle; but it ispreferable to have them in separate pieces.

I claim- 1. The combination ofthe ferrule d, the mass c of bristlesextending within it, and the two strips a a, inserted in the saidferrule and mass IOO and connected thereto by nails e e, driven intothem and the two` strips, and clinched by a metallic plate, I), placedbetween such strips,

with a wedge, f, driven between such strips,

5 so as to force them asnnderwithin the mass of bristles and tighten itin the ferrule.

2. The combination of the ferrule having channels and wires therein inthe lower parts of its sides, as described, the mass of bristlesextending within it, and the two strips ay a, inserted in the saidferrule and mass and connected by nails driven into them and the twostrips, and clinched by a metallic plate placed between the latter withawedgqf, 15 driven between such strips, so as to force them asnnder andthe bristles against the sides of the ferrnle and the wires placedtherein, all being substantially as set forth.

3. The combination of the handle placed and fixed in the upper part ofthe ferrnle,with such 2o JoHN FRANCIS BowDrreH.
